Before clamping and fixing the metal contact each time, the arc-shaped scraper 5 is controlled by a lifting assembly 6 to scrape the inner wall of the clamping plate 3 to avoid debris adhering to the inner wall of the clamping plate 3, thereby preventing the clamping from being unstable and damaging the outer surface of the metal contact, and the arc-shaped scraper 5 is connected to the lifting assembly 6;

[0025] The clamping drive assembly 2 includes a primary motor 21, which is connected to a gear 22 via a motor shaft. The gear 22 is meshingly connected to two correspondingly arranged racks 23. The ends of the racks 23 that are away from each other are fixedly connected to a moving rod 24. The top of the moving rod 24 is fixedly connected to an L-shaped rod 25, and the end of the L-shaped rod 25 is fixedly connected to the clamping plate 3.

[0026] Specifically, a pressure sensor 7 is installed at the connection position between the clamping plate 3 and the L-shaped rod 25. The pressure sensor 7 can detect the pressure exerted on the metal contact during clamping and fixing, so as to control the clamping force and avoid deformation of the metal contact caused by excessive clamping force.

[0027] Furthermore, the lifting assembly 6 includes a fixed frame 61, on which a secondary motor 62 is installed, the output end of the secondary motor 62 is connected to a screw rod 63, a positioning slide rod 64 is provided on one side of the screw rod 63, a moving block 65 is connected between the screw rod 63 and the positioning slide rod 64, and the moving block 65 is fixedly connected to the arc scraper 5 through a connecting plate 66.

[0029] It is worth mentioning that a limiting slide groove 8 is provided on the rack 23, and the limiting slide groove 8 passes through the moving rod 24. A limiting slide rod 9 is provided in the limiting slide groove 8. Both ends of the limiting slide rod 9 are fixedly connected to the inner wall of the base 1. The limiting slide groove 8 and the limiting slide rod 9 limit the movement trajectory of the rack 23, so that the rack 23 moves along the axial direction of the limiting slide rod 9.

[0030] It is worth noting that two corresponding bar-shaped through slots 10 are provided on the top of the base 1 , and the L-shaped rod 25 passes through the bar-shaped through slots 10 .

Under the restriction of the limiting slide groove 8 and the limiting slide bar 9, the rack 23 and the moving rod 24 fixedly connected thereto move along the axial direction of the limiting slide bar 9, thereby driving the L-shaped rod 25 to approach each other, so that the clamping plate 3 can clamp and fix the metal contact. At the same time, the pressure sensor 7 can detect the pressure on the metal contact in order to control the clamping force. When the metal contact is clamped, the pressure sensor 7 can detect the pressure on the metal contact in order to control the clamping force. After fixation, tapping work can be carried out. After the tapping work is completed, start the first-level motor 21 for reverse movement, so that the clamping plates 3 can move away from each other, and the metal contact can be removed. At this time, the position of the clamping plate 3 corresponds to the position of the arc scraper 5. Start the second-level motor 62 of the lifting assembly 6, and the screw rod 63 rotates. Under the positioning slide rod 64 and the threaded structure, the moving block 65 moves up, and then the connecting plate 66 drives the arc scraper 5 to move up, so as to clear the debris attached to the inner wall of the clamping plate 3, avoid the debris affecting the stability of the metal contact clamping and damaging the metal contact, which is beneficial to the clamping and fixing of the metal contact.
